This includes the following changes:
- Report an error if a file name is empty.
- Make '-o' behave like '-c', but writing to file instead of stdout.
- Do not open output if input is a terminal.
- Replace 'decompressed', 'compressed' with 'out', 'in' in output.
- Several fixes and improvements, improved test coverage.
On the way switch from PORTVERSION to DISTVERSION and add a LICENSE_FILE
(while the license itselfs does not change from GPLv2).
